en.Wedoany.com Reported - EEW, the operator of the Hanover-Lahe waste-to-energy plant, and municipal energy company enercity have reached an agreement to increase the plant's district heating capacity without raising the amount of waste processed. The two parties signed an agreement in early 2025 to boost the usable heat from the current 50 MW to up to 85 MW through turbine bypass and other energy efficiency optimization measures.

The optimization measures include allowing steam to bypass the turbine and flow directly into the district heating network when heating demand is high, and switching to combined heat and power operation in other operating modes. This reduces heat loss and increases available energy supply, while correspondingly lowering electricity generation when heat extraction is maximized. The initial retrofits are part of the plant's current comprehensive overhaul, with all work scheduled for completion in the second quarter of 2027. The additional heating capacity will be available for the 2027/2028 heating season. enercity has also invested in expanding the pipeline network to ensure the increased heating capacity can be distributed throughout Hanover.

enercity plans to integrate the optimized plant into its diversified heat and power portfolio as a flexible peaking unit. Depending on actual demand and market conditions, the plant can prioritize either heat supply or power generation, thereby ensuring supply security during cold weather and enabling market-based operations.
